I checked the RBA website for stork sightings this month. There is a strong case to suggest a bird seen at various places in Suffolk and beyond, during the week, which has settled at Aldeby, is a vagrant. [/Quote]
Birders not present consider the bird to be a good candidate for an escaped indivdiual. It has been suggested that the Thrigby birds do indeed venture all over the place including locations much further away than this - as do various other escaped or free-flying White Storks.......
I didn't check any website for stork sightings this month but I think there is only a strong case to suggest a bird has been seen at several places in Suffolk and beyond, not that it is a vagrant......
All that said, I actually think it might be wild. It's a good time of year for vagrants to turn up and the conditions are suitable. If you're going to tick any White Stork that doesn't have some real proof of wild origin like an appropriately-traced ring (as I have) then you might as well tick this one. But don't be surprised if it flies north for a few miles and then drops down in the Thrigby area.

There were 6 White Storks in captivity at Thrigby Wildlife Gardens 10 years ago when I started checking the collection to monitor the storks. One of them was a free flying individual that often wandered off in the spring and summer.
That bird died or disappeared about 7 years ago but was replaced by another free flying individual. I believe the keepers there always allow one of the storks to be free flying every year but wing clip the remaing birds so that there is always a free flying bird about the collection. Previous individuals often sat on the artificial stork nest on the roof of the main building.
In recent years when there have been sightings of White Stork in areas away from Thrigby I have tried to check the collection. When checked, I have inevitably found one stork to be missing from Thrigby at the same time.
Gradually the number of birds has declined (whether they have wandered off or died is not known) and this winter there were only 3 remaining storks - one of which was free flying. I last checked in March this year and all three birds were still present.
I checked today and only two clipped birds are present at Thrigby - the free flying bird has gone missing.
These are the facts so you can make your own assumptions and judgement on whether the bird moving up and down in East Norfolk and Suffolk at present is likely to be a wild bird or not.
One additional comment - none of the birds are ringed and the free flying bird is usually full-winged.
